Faster Version with the new bech32-fast library?

[gitmachtl]

hey @KtorZ , would it be possible to get a new version here with the faster bech32 library you have built?

[KtorZ]

Possibly, but it may be difficult since the API of fast-bech32 is actually quite different from this one... Simplified, but also arguably less typesafe. So, porting part of the (optimized) implementation while preserving the current API isn't trivial..
